When Accessories Become Essentials

In my almost three decades of home ownership, I’ve learned a great deal about maintenance in regard to dwelling structures. Among those lessons are:

  • The importance of the right tool(s) for the job.
  • Having the right materials on hand (I’m looking at you, every plumbing project I’ve ever attempted).
  • When it’s a one-person job, a team effort…or a call to the professionals is always in play.

When it comes to EXAIR Intelligent Compressed Air Products, the first and last concerns above are easily addressed. With precious few exceptions, basic hand tools are all that’s required for installation or maintenance, and they’re engineered & manufactured to be “user friendly”. One key aspect of the “user friendliness” is a comprehensive inventory of accessories.

Some of these accessories are unique to a particular Product Line:

  • Air Knife Plumbing Kits are great, especially for the longer Super Air Knives that need to be plumbed to multiple ports along their length. These consist of air hose and brass fittings (for Aluminum Super Air Knives) or Stainless Steel tubing and fittings (for the Stainless Steel models) that connect in to those multiple ports, allowing for infeed to just one (for Super Air Knives up to 54″ long) or two (for lengths up to 108″) 1/2 NPT fittings. These can actually be used on our Super Ion Air Knives as well.
  • Universal Air Knife Mounting Systems provide for ease of installation, and precise positioning of our Aluminum or Stainless Steel Super, Standard, or Full Flow Air Knives.
  • Coupling Bracket Kits can join Super Air Knives together for a continuous, uninterrupted curtain of air flow in any length that you need. They can also be used if you don’t always need air flow along the entire length of a Super Air Knife assembly. I had the pleasure of assisting a user once who had needed to blow off parts on a hanging conveyor. Some parts were a little under 2ft long; others were about 4ft long. They used the Model 110900 Coupling Bracket Kit to join two Model 110024 24″ Aluminum Super Air Knives together, plumbed them separately, and turned both of them on for the long parts, and just the ‘top’ one for the shorter parts.

Other accessories can be used for a variety of products:

  • Stay Set Hoses (with or without Magnetic Bases) make up instant Blowoff Systems when used with our engineered Air Nozzles. They come in lengths from 6″ to 36″, and can bent by hand to “stay set” (as advertised) to hold their position. They can repositioned, as needed. They’re also popular for use with our 3/4″ and 1-1/4″ Super & Adjustable Air Amplifiers, and can even be used with 3″ Air Knives.
  • Conveyance Hose is a great way to connect point A to point B in a Line Vac Air Operated Conveyor system. Bulk material conveyance really doesn’t get much easier than Line Vac + Hose = Instant Conveyor System (just add compressed air). It can also be used with our Air Amplifiers to duct or route the air flow on the inlet, or the outlet to, or from, one area to another.
  • Mounting Brackets are available for a number of our products:
    • Atomizing Spray Nozzles
    • Line Vacs
    • Filters and Regulators
    • Cabinet Cooler System Thermostats
  • Vacuum Cups are often used with our E-Vac Vacuum Generators for pick-and-place material handling applications. We stock fittings and push-in tubing as well, to complete the package. Those fittings and tubing can also be used for the liquid supply to our Atomizing Spray Nozzles (depending on what you’re spraying, you might want to verify chemical compatibility first; call me if that’s a concern).

Other EXAIR Compressed Air Product Accessories can be used with products that aren’t even ours, or, in conjunction with your compressed air system design for increased efficiency or flexibility:

  • Model 9500-60 60 Gallon Receiver Tanks can be installed near points of high air flow demand to prevent or limit fluctuations in supply throughout the system.
  • Compressed Air Hoses can be made to length, and a variety of Fittings (Hex or Close Nipples, Couplers, Reducers, Tees, Elbows, Crosses, and Bulkhead Fittings) are on the shelf in popular sizes.
  • Our 5 Micron water/dirt Filter Separators are a standard when needing clean, condensate free air to blow through and end-use product.
  • Pressure Regulators are an important factor to minimize compressed air consumption. EXAIR always recommends operating our products at the minimum pressure necessary for a successful application. For example, if using a Super Air Knife to remove dust and light debris, this could be achieved at 20 PSIG, a Pressure Regulator will provide that adjustability and keep the air consumption much lower than if it were operated at 80-100 PSIG.
  • Swivel Fittings, typically used with compressed air nozzles, provide the precision adjustability to focus in on the exact area you need to treat.

If you have any questions about how the above accessories can aid with your application, please relay on our expert team for answers and solutions. Having the right materials and accessories on-hand can simplify installation, enhance performance, save compressed air, and more!

Building Flexibility with Stay Set Hoses and Magnet Bases

You can build in flexibility when purchasing Super Air Nozzles, Air Knives, Safety Air Guns and other products from EXAIR. Consider adding our Stay Set Hoses and Magnet Bases to create flexibility and ease of set-up to your process. These accessories will improve your project and reduce your set-up time.

EXAIR has a variety of lengths in our Stay Set Hoses ranging from 6″ up to 36″ in 1/4 MNPT x 1/8 FNPT or 1/4 MNPT x 1/4 MNPT fittings. The Stay Set hoses are used mainly where frequent repositioning is required. You can bend and the hose to your desired position and since the hose has “memory” it will not creep or bend. It will keep this position until physically moved to the next position. These hoses can withstand temperatures up to 158 F (70C).

EXAIR Magnet Bases can be used when frequent movement of air product is required. These powerful magnets permit horizontal or vertical mounting. A valve is used to vary force and flow. The choice of single outlet, dual outlet and Swivel are available.

The combination of our Stay Set Hoses and Magnet Bases will accommodate Air Nozzles and Jets along with our smaller Air Knives, Air Wipes, Super Air Amplifiers and can also be assembled to our Safety Air Guns. There are many uses for our Stay Set Hoses and Magnet bases. While purchasing our Intelligent Compressed Air products consider all of our accessories to help your projects. If you have an application and have questions please contact EXAIR and one of our Application Engineers to answer your questions.

Turn the Pressure Down, Save Operation Costs

I recently recommended to a customer to turn their air pressure down on their system as low as their process would allow. Meaning regulate the pressure so you have enough to complete the operations needed but find that happy medium where your compressor isn’t working as hard to build those high pressures for no reason!

Compressed air is an amazing tool to have, and when used properly it can be more efficient that other non compressed air tools that run off electricity. How ever its pretty common to see compressed air systems running at their max just because.

Lowering the air system pressure reduces the compressor power consumption by about 1% for every two psi of lower pressure. Lowering the pressure also makes any unregulated operations reduce consumption by almost 1% for every one psi of pressure reduction. Not to mention the extra savings if your compressor system can turn down the compressor power because of the reduced flow and possibly shut off compressors that are no longer needed!

The best pressure at which to set your system is the level where your production can operate efficiently and effectively without waste: There is no right pressure—it depends on your operations and tools. You may have 90 to 100 psig at the compressor, but at the production machine, where the actual work is being done, you could have only 65 to 70 psig. In some cases, it may be even lower due to pressure drops in undersized piping, filters, regulators. The goal is to lower compressor discharge pressure without affecting the the operations at the end of the line.

Having artificially high plant-pressure can help you deal with surges in compressed air demand that might occasionally cause low-pressure and affect production. The higher pressure acts to store reserve air in the various volumes made up of receivers, pipes and such in your system. However, the higher pressure costs more to produce and makes unregulated end uses consume more air, which is an expensive trade-off. Another option is to make sure you have line pressure regulators at each point of use. This will allow you to regulate the operation to the pressure needed being sure to save compressed air and keep the over all system running more efficient.

You can regulate those point of use lines with a number of EXAIRs Pressure Regulators!

EXAIR offers a range of Pressure Regulators capable of handling air flow of up to 700 SCFM.

If we can help size a regulator, or have any other questions on how EXAIR can help you save compressed air in your system please reach out to me or one of our other Application Engineers!

Silencing Mufflers

I live near an amusement park called Kings Island. In the later part of Spring I can hear and see the people and rides. As the Summer enters and the tree leaves have all grown they act like a muffler reducing the roller coaster noises and screaming people on the roller coasters. These trees are not high enough to block the nightly fireworks but this is a good thing for me as I enjoy the sights and sounds of the fireworks.

An important focus in every manufacturing environment is a “Noise Reduction” campaign making a safer and healthier area for people working in the environment. EXAIR has Silencing Mufflers that can support your efforts for noise reduction. We have a variety of mufflers which will help to reduce work area noise produced by air exhausting from cylinders, valves and other air powered equipment. EXAIR Silencing Mufflers help plants meet OSHA Standard 1910.95(a) by reducing the sound to safer levels. Not only do our Silencing Mufflers reduce sound but they also eliminate harmful dead end pressures by covering up an open port or opening. These openings do not have a pathway for harmful pressurized air to escape if they become blocked.

Sintered Bronze Mufflers: A low cost solution and easy to install in new and existing air powered products. Sintered bronze muffler come in a variety of sizes (10-32 thread size up through 1/2-20 UNF female) and are capable of passing a certain volume of air with minimal back pressure restriction.

Reclassifying Mufflers: These mufflers are an upgrade from Sintered Bronze Mufflers. They offer the best noise reduction, up to 35 decibels. Available from 1/8 NPT up to 1 NPT. Reclassifying Muffles also eliminate oil mist. The patented wrap design of the removable element separates oil from the exhausted air so virtually no oil is released into the environment.

Straight-Through Mufflers: These mufflers offer a corrosion resistant aluminum outer shell lined with sound absorbing foam for better noise reduction. The typical noise reduction is up to 20dB.

Heavy Duty Mufflers: feature a corrosion-resistant aluminum outer shell with an internal stainless steel screen that protects valves and cylinders from contamination that could enter through the exhaust ports. The typical noise reduction is up to 14 dB.

EXAIR can help in your noise reduction projects with many options to consider. If you have any questions or need help selecting the right muffler for your needs please contact any of our qualified Application Engineers.
